At one point in the 1980s, it was estimated that the cost of residential electricity in Seattle was one tenth the cost in New York City. If it’s any consolation, our delicatessens weren’t anything to write home about. The cost differential isn’t that great anymore, but we’re still below the national average. Lower costs aren’t necessarily a justification for excessive use of electricity, but they will determine whether more efficient fluorescent lamps will ever pay off for you.
Basically, the higher your electricity costs run beyond the national average (around 8￠ per KWH), the more cost-effective fluorescent lights will be in your home. This doesn’t mean they will work well for all your lighting needs from a cost standpoint. The longer a light is continually on, the better a candidate it is for a fluorescent lamp. An occasionally used attic or storage-room light is best left with an incandescent lamp. Some fixtures, such as recessed ceiling lights, might not have room for a fluorescent lamp.
